your into the wrong section buddy... 200sx in this thread are B14 !!.... yours an S12... from the great RWD Sylvia familys !!....

www.s12.org... i might be wrong here... ill post it tommorow morning, im at the job so.....
Easiest swap there is the Ca18det from the S13 wich share most of the chassis... the Vg30 will be a pain in the A$$ to put in there if you dont have a donor because of engine mount, wiring ect... the Ca18det will bolt right into it.. plus will be less messup with your wiring...
